I went there with some friends to see an immense telescope, which he has made almost entirely without aid, preparing the glasses as far as possible himself, and sending them away merely to have their concavity changed.

He showed us all his treasures with the greatest delight, explaining in English, but substituting Welsh when at a loss.

He has scarcely ever been at school, but has learnt English entirely from books.

Among other things he showed us were a Greek Testament and a Hebrew Bible, both of which he can read.

His largest telescope, which is several yards long, he has named 'Jumbo,' and through it he told us he saw the snowcap on the pole of Mars.
